Fox has unveiled the poster for the fifth and final season of Fringe showing Peter Bishop, Olivia Dunham and Walter Bishop depicted in graffiti as revolutionary icons in the year 2036. The series returns Friday, Sept. 28.

Fringe Executive Producer Joel Wyman and stars Josh Jackson, Anna Torv, John Noble and Jasika Nicole reflected at Comic-Con International on four years of the show and prepare for their curtain call in September.

While co-creator J.J. Abrams remains “hopeful” about the future of Fringe, Fox President Kevin Reilly acknowledges “we’re not in the business of losing money.” Star Joshua Jackson, meanwhile, only hopes that the writers will be able to give the series a proper ending.

A major milestone in both the season and the series was reached on tonight’s all-new episode of Fringe — but progress doesn’t come without its costs, and this time, it came at the expense of a main character’s life.
